Taken from the internet, these are the proofs about the world ending. (If you are reading this, obviously it did not happen.)
The first proof is based on Genesis 7:4, when God said to Noah: "Seven days from now I will send rain on the earth for forty days and forty nights, and I will wipe from the face of the earth every living creature I have made."
When God referred to seven days, he meant both seven days and seven thousand years, because "one day is with the Lord as a thousand years, and a thousand years as one day." The flood occurred in 4990 BC. Seven thousand years later is 2011.
